I attach a couple of pictures who describes in pictures a modification to a BOSCH 55 Amps alternator, the three lights really beam-flashes now.
The fix is a easy way to do, just dismantle the front cover and weld a ring ( i can give you the measurement) machine the cover in a mill or turn it in a lathe to 110mm I think it was. then bore a new thread holes, Then the shaft must modified the, I don't remember what it was. But I can give you the exact drawing on the job if you want. it was my father who did the job last summer. And it works perfect, And NO the plastic cover DOES NOT move forward, it depends on that he welded the ring a little bit backward so it was lots of materials to turn away and lot of materials to dip down the alternator in.
I attached more pictures to explained for you, maybe you understand (my English isn't so good)
As you see the BOSCH original alternator shaft must turn away some materials, turn a cone that match as in a actual length. It must match the surrounded alternator. and the surrounded alternator dips in the cover, about some measure that I don't remember, but if you want to know, don't hesitate to contact me in an week or something, then I have heard with my father about the right way to do. Then maybe you can let someone do it in a factory. /Tord
